Definitions

  • the present invention relates to a cutting machine that can be used in agriculture, arboriculture or viticulture, comprising a cutting head having at least one pair of modules, according to the preamble of independent claim 1.
  • this machine can be provided with a device allowing the operator, whenever he deems it necessary, to sharpen this tool on site.
  • the invention focuses essentially on the entire lower part of the cutting machines of the aforementioned kind in order to significantly improve their operation and comfort of use.
  • EP-A-0 147 344 discloses a cutting machine of which at least one of the two cutting modules may comprise a tool inclined forward and formed of two disks pressed against each other to produce a shear cut.
  • One of these disks connected to a vertical upright of a bearing structure of the cutting module, is fixed and has at its periphery, on a defined circular arc, an alternation of teeth and notches.
  • the other disc is rotated like the toothed and ribbed disk of the cutting tools of the cutting module and has an alternation of teeth and notches throughout its periphery.
  • the spool tool (like all other tools that this machine is equipped with) has a fixed element and a movable element to produce shear sectioning.
  • EP-A-0 696 416 discloses a cutting machine having a cutting module and a feeding module.
  • the lower cutting tool is similar to that of the tools stacked above it, that is to say essentially consisting of a circular saw rotated at high speed and a cage surrounding it entirely. , also driven in rotation, but at a speed whose tangential component corresponds approximately to the forward speed of the tractor to which the machine is coupled.
  • the saw teeth of this lower cutting tool is substantially thinner than that of the upper saws.
  • This machine can also be equipped with a specific tool according to EP-A-0 696 417 to spare spurs, but does not have the function of producing a cut.
  • the objectives (2) and (3) are achieved, but the user must however accommodate a cutting quality (objective (1)) questionable.
  • the objective (4) (comfort of use) is not the object of particular criticism, since the questions of a restoration and even less of a premature replacement of the lower cutting tool practically do not arise.
  • EP-A-1,825,744 discloses a cutting machine which may be provided with an optional tool which differs from the cutting tools arranged above it, in that it comprises two elements cooperating with one another and consisting essentially of one a fixed plate, connected to the carrier structure of the module and having on a defined sector oriented towards the front of the fingers and the other, a rotated disc, whose entire periphery is provided with an alternation of sharp knives and indentations.
  • the fingers of the fixed plate emerge out of the outer circle determined by the end portions of the knives, so as to channel the branches and ensure the maintenance of the latter just before the cut occurs, which is produced by shearing and without breaking of the courson.
  • US-2006/0162309 describes a cutting machine of the commented kind, the result of a juxtaposition of known means, in particular EP-0 147 344 and of EP-0 696 416 .
  • Each of the two cutting modules has at its bottom a spur tool essentially comprising two elements.
  • a first toothed disk member is rotated.
  • a second element also has a general disk shape. Constituted, on a sector of about 180 ° each time, a toothed portion facing the other module and a non-toothed portion serving protection, this second element is fixed.
  • the diameter of this tool to courson is "slightly lower" to the diameter of the cutting tools of the module arranged above him, in order to decrease the risk of engagement of objects at this level.
  • the two elements cooperate with each other to produce a shear cut.
  • the object of the present invention is to propose a cutting machine of the type of those commented, which is, on the one hand, provided with at least one tool with courson to achieve cumulatively the objectives (1) to ( 4) listed above and, on the other hand, optionally equipped with a device for sharpening this tool to achieve the objective (5), this device can be implemented as needed and very good on the parcel or at the very place where the machine is moving momentarily, so that the initial quality of the bobbins is always maintained, over a long period of time and without any other intervention, the machine is immobilized in a workshop. imposing itself more than for the sole purpose of an imperative replacement of a tool with a spur that has reached an irretrievable threshold of wear, which occurs, in viticulture for example, after pruning or pruning on an average surface of the order some 800 hectares.
  • the cutting head shown in figure 1 corresponds to that described in EP-A-1,825,744 , to which this example refers: it consists of two cutting modules [A], [B], axes A1, B1, substantially vertical, carried by a frame 8 can be coupled to a tractor (not shown), with pivoting abilities about axes A2, B2, respectively, parallel to the axes A1, B1, and to be rotated under the action of hydraulic motors 9 and 10 (arrows R (A) and R (B)), preferably at speeds in the range of [250 - 300] rpm, the speeds of rotation of the two modules being able, but not necessarily, to be equal to each other.
  • Each cutting module rests on a support bearing 5; 6 and is formed of at least one cutting tool, usually a stack of a plurality of tools 3; 4 whose periphery has active elements, that is to say elements directly involved in the cutting operation, in this case teeth (not referenced), the tools of a module can interpenetrate in defined spaces e1 arranged between the tools of the other module, so as to allow said modules to adopt any appropriate positions between maximum positions of opening and closing during the implementation of the machine and more particularly during the operations of chopped off.
  • the modules cooperate with each other in that they channel the vegetation in a median space where it will be reduced to a plurality of sections.
  • each cutting tool makes its cuts, whether by shearing or sawing, independently of any other cutting tool of the other module, a cutting tool comprising, as a rule, two elements of which at least one is rotated.
  • each cut results from mutual actions, and therefore from an interaction, between a cutting tool 3 of the module [A] and an associated cutting tool 4 of the module [B].
  • These tools 3, 4, identical, of defined height h advantageously greater than 3 mm and preferably equal to about 15 mm, are each arranged inversely with respect to each other, the quality of the cut being adaptable by adjusting a space e2 between the upper and lower faces (not referenced) of cutting tools 3, 4 associated.
  • the lower tools of the modules [A; B], that is to say, according to the arrangement of the figure 1 , the spur tool 1 and the cutting tool 4, and, depending on the arrangement of the figure 3 , the courson tools 1, 2, are mounted under the bearing bearings 5, 6, so as to avoid any damage that may cause the shock, including the courson, a part of the machine.
  • the spool tool 1 of the stack of tools of the module [A] differs from the other tools 3 stacked above it, in that it is formed of a circular disk of thickness ⁇ , of which the periphery is bevelled to form a continuous cutting edge 14 (the bevel 13 being oriented downwards, in other words, the apex of the cone whose envelope contains this bevel is located under the stack of the module, by definition on the axis A1 of it).
  • the value ⁇ , relatively small in comparison with the height h preferred tools 3, 4 is advantageously in a range of about 3 to 6 mm, and preferably equal to 4.0 mm or 4.5 mm.
  • the plane Ps (1) of the upper face 11 of this tool 1 extends under the plane Pi (4) of the lower face of the first cutting tool 4 of the stack of the module [B], these two parallel planes Ps (1), Pi (4) being separated by a distance ⁇ constituting a functional game, easily adjustable through a known adjustment device 7. Numerous tests have shown that the value ⁇ is advantageously in a range of about 1 to 4 mm.
  • the outer diameter D (1) of the spur tool 1 is smaller than the base diameter Dp (3) of the cutting tool 3 (hence of the diameter from which the aforementioned active elements emerge, namely the teeth), which, in addition to providing a quality cut, avoids any collision of the peripheral cutting edge 14 of the tool courson 1 against the trestle posts, even strongly inclined, therefore any damage to these and tool 1 itself.
  • the difference (Dp (3) - D (1)) is equal to 2 ⁇ , the value ⁇ advantageously being in a range of about 0.1 to 20 mm and preferably equal to about 5 mm.
  • the foot circumference of diameter Dp (4) of the cutting tool 4 overflows the outer circumference of diameter D (1) of the tool of courson 1, over a length ⁇ , which ensures a smaller size of the branches well completed and therefore eliminates any risk of chipping of the courson thus formed.
  • the value of ⁇ is advantageously in a range of about 15 to 50 mm and preferably equal to about 30 mm.
  • the trellising wire is subjected, throughout the course of the cutting operations, to different forces, the resultants act on it so that it can only slide or evolve under the face 12 of the tool 1, or on the upper face (not referenced) of the cutting tool 4 with which said tool to courson interacts to produce the section, or, more sporadically, between the face 11 of the tool 1 and the lower face (plane Pi (4)) of the tool 4, or, finally, to move from one of these states to another, but this, without ever being able to be hung or sheared.
  • the figure 3 which is a partial perspective of the front of the cutting machine, shows a mounting variant according to which the lower tool of the module [B], arranged under the bearing 6 ( figure 1 ), is also a tool to courson.
  • the latter, reference 2 is identical to the tool to courson 1, except that it is mounted in a position opposite to that of the tool 1, the plane Ps (1) of the face 11 (see also figure 1 ) extending under the plane (not shown) of the face 21 of the tool 2, the bevel 23 being, unlike the bevel 13, facing upwards.
  • a clearance ⁇ separates the planes of the faces 11, 21 of the tools 1, 2 respectively.
  • the Figure 2B is a view from below of the figure 3 . It is analogous to the Figure 2A , so that the explanations given in support of the latter, in particular those concerning the parameters ⁇ and ⁇ , apply mutatis mutandis. It will be observed only that the size of the spurs results from the interaction of the active parts 13, 14; 23, 24, in particular cutting edges 14, 24 of courson tools 1, 2 producing a shear cut. However, the cut of the courson intervening at the intersection of the cutting edges 14, 24 (the zone Z extending, according to this mounting variant, around this intersection), can be performed on two levels. If it remains in itself of excellent quality, it is likely to be staged, at least on some coursons, the distance between the two cutting planes on the spur corresponding approximately to the value ⁇ .
  • the lower tool of one of the modules will be a tool to run 1 or 2 arranged so that it is able to interact with a lower tool of the other module and that all the conditions, in particular geometric, described above, are respected.
  • this lower tool of the other module could be of the type of the tool 4 or 3, or a tool with courson 2 or 1. It is understood that the assembly of two tools with courson 1, 2 is not deprived of interest for all these other kinds of cutting machines.
  • the figure 4 shows a runner tool as a possible alternative embodiment.
  • This tool has a discontinuous cutting edge 18, in that it is distributed over a succession of bevelled sectors 16 of angle ⁇ , each having a bevel 17.
  • the cutting edges 17 are slightly curved and are subsequently connected one to the other.
  • Another means of a segment 19. In order to avoid any attachment with a surrounding element, during its rotation, it is important for this tool 15 to be mounted so that said segment 19 does not appear against the direction of rotation R. This is on the contrary, each incurvation 17 which follows this direction.
  • the tangential component of the rotational speed of the tools of one module is greater than the tangential component of the rotational speed of the other one module, which allows an optimal ejection of the segments of shoots cut out of the trellis son , especially of those who are wrapped around these.
  • the highest rotational speed be applied to this module.
  • the relative difference between these tangential components is equal to a value ⁇ and is preferably in a range of about 20 to 40%.
  • the sharpening device consists of means that can be grouped, functionally, into four subgroups, namely a sharpening block, a set connecting elements connecting this block to the cutting machine and allowing it to be moved from a passive (ie waiting) position to an active (ie working) position and vice versa, a set of adjustment means of said block relative to the lower tool to be sharpened to ensure a correct sharpening and quality of this tool and, finally, means for actuating and guiding the block, necessary to perform sharpening operations.
